1. Analysis of the effects of environmental factors (temperature, light, water content and CO2 concentration) on the photosynthesis activity of two common Antarctic mosses and a cyanobacterial mat in the Taylor Valley [K024_2002_2003_NZ_2]
A detailed study of how the environmental factors temperature, light, water content and carbon dioxide concentration affected photosynthesis of the two common mosses Bryum argenteum and Hennediella ...


2. Comparison of the photosynthetic performance of Umbilicaria species in the Ross Sea region [K024_2002_2003_NZ_3]
The photosynthetic performance of Umbilicaria species was measured under standard conditions in the laboratory and compared with Umbilicaria species from the Taylor Valley and Mt Kyffin.


3. Examination of the photosynthetic behaviour (energy content, nutrient content, productivity and acclimation) of mosses and lichens throughout the summer season at Cape Hallett [K024_2004_2006_NZ_2]
A possible sign of climate change is likely to be improved production and growth in plants. The response of net photosynthetic rates were measured on the large areas of relatively uniform moss cover ...


4. Microclimate measurements (air temperature, light levels and relative humidity) near vegetation at Botany Bay, Granite Harbour [K024_1999_2000_NZ_1]
Several data loggers were deployed in and around plants in order to obtain more information of conditions at the plant level to be able to determine if plants performance characteristics are adapted ...


5. An estimate of the production rate of 14CO due to natural cosmic ray background [K087_1994_1995_NZ_1]
14CO measurements in cylinders exposed in Antarctica were used to estimate the production rate of 14CO due to natural cosmic ray background with comparisons with similar exposures in the Southern ...


6. Experimental measurements of the production rate of 14CO in high pressure air samples [K087_2003_2004_NZ_1]
Air samples are collected from Arrival Heights for analysis of trace gas concentration and isotopic composition throughout the year. The high pressure samples that are collected from February through ...


7. Measurements of the production of 14C in cylinders in Antarctica [K087_1992_1993_NZ_1]
In order to measure the production of 14C via 14N (n,p) 14C, cylinders with ultra pure air doped with dead CO were exposed at Scott Base and the South Pole.


8. Hydrological and meteorological measurements (air temperature (at 1.5m and 10m), relative humidity, windspeed and direction, net radiation, solar radiation and snow heat flux) on the McMurdo Ice Shelf [K162_1990_1991_NZ_1]
Meteorological and hydrological variables were measured in the ablation zone of the McMurdo Ice Shelf (MIS) to characterise and quantify the energy and water budgets of the MIS in areas where biological ...


9. Chlorophyll a fluorescence and temperature measurements from lichen and mosses buried under snow at Botany Bay, Granite Harbour [K024_1999_2000_NZ_2]
Fluorescence (chlorophyll a fluorescence) activity measurements were recorded for selected plants for about three weeks to determine if the photosystems of lichen or mosses are active in differing ...


10. Measurements of atmospheric aerosols from air and snow samples and meteorological measurements taken from a remote site on the Ross Ice Shelf [K093_1989_1990_NZ_1]
The chemistry of air and snow at a remote site on the Ross Ice Shelf was conducted to study atmospheric aerosol particulates which are of interest as they may be important regulators of climate and ...


11. Measurements of photosynthetic recovery after the winter cold and desiccation at Botany Bay, Granite Harbour [K024_2000_2001_NZ_1]
Three CMS400 photosynthesis systems were used to study the recovery of photosynthetic activity by lichens and mosses rewetted for the first time after the winter at Botany Bay, Granite Harbour.


12. Measurements of spectral transmission and backscattering of light in first year sea ice, Tent Island, McMurdo Sound [K132_1985_1987_NZ_1]
In situ measurements of the the spectral transmission and backscattering of light was conducted on first year ice to characterise the optical properties of sea ice. The average scattering length and ...


13. Measurements of the shielding against UVA by protective pigments in the moss Bryum subrotundifolium at Botany Bay, Granite Harbour [K024_2000_2001_NZ_2]
A new chlorophyll fluorescence system, UVA PAM allowed the protective shield against UVA radiation to be measured in the moss Bryum subrotundifolium. An area of the moss was heavily shaded for 10 ...


14. Nutrient transfer from penguin colonies to the vegetation at Cape Hallett: A measurement of the transfer of organic nitrogen in the form of ammonia [K024_2004_2006_NZ_3]
The transfer of nutrients from marine to terrestrial ecosystems are though to be important for vegetation. The transfer rate of organic nitrogen in the form of ammonia from the penguin colonies to ...


15. The distribution of path lengths taken by light as it scatters through sea ice [K132_1990_1993_NZ_1]
The spatial spreading of light introduced at a point on the surface of the ice and the temporal spreading of a brief pulse of light injected at a point was measured to clarify the details of the interaction ...


16. The structure (temperature, salinity, density and heat capacity) and transmissivity of sea ice [K132_1989_1990_NZ_1]
The transparency of sea ice to UV radiation was measured to determine the effects of enhanced UV levels on Antarctic life. The under ice radiance is controlled by the transmission of the sea ice to ...
